There were a number of teams at Championship that saw 0.00V battery readings, yet had their robots function. The primary causes were: not having the Analog Module installed in slot #1 of the cRIO, not having the appropriate jumper installed on the analog breakout board, or a bad connection between the analog breakout board and the PDU. In all cases, the lack of a correct battery voltage reading did not affect the robot performance.

Even though its an inspection item, the battery voltage reading is just a diagnostic tool. Some teams having robot issues on the field were informed by the FTA (or FTAA) after a match that their battery voltage was dropping to very low values (<8V). Bad batteries can cause radio or cRIO resets, which result in loss of communications on the field. Not a good thing...
